Summary

This study aims to develop a non-invasive blood test that analyzes fetal DNA found in the mother's blood to determine paternity. It is designed for sexual assault victims who become pregnant and need to know the father's identity for legal reasons. The test uses a technique called massively parallel sequencing and will be tested on 60 pregnant women and their potential fathers. If successful, it could replace invasive procedures like amniocentesis.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could provide a reliable, non-invasive way to determine fetal paternity in criminal cases, helping victims avoid invasive procedures.
What could go wrong
This is a small, early-stage method development study (60 participants). The technique may not be accurate enough or may fail to work in all cases. Results are for forensic use only, not a medical treatment.
